When it comes to friendly or even just civil camaraderie, you should NEVER have to be someone's bitch (helping out a drummer pack and carry his stuff without acknowledgment or thanks) as a substitute for their lack of social skills.
I disagree, my friend. IME, to have a friendly relationship develop often requires humility. The attitude that you might "be someone's bitch" comes from a place of fear motivated by pride. I know that you don't necessarily want to jump on the grenade for every d*bag, but if there's on thing I've learn from marriage it's that it's not necessary to always be trying to
assert our rights. You know?
It takes courage to endure some ungratefulness for awhile in the hopes that it'll make a difference. Sometimes, it doesn't make a difference--but if we don't have the patience and the courage to try it, we'll never know. It's not important to always be concerned with asserting your rights and demanding respect. If everybody wants respect and no one wants to be friendly, where will we end up? We'll end up with neither respect or friendship.
I'm just saying someone has to be the adult. Someone has to take the first step. The bassist didn't say that he needed anyone to help him carry his stuff. The only one offering the opportunity to help is the drummer. So, I'm saying take the opportunity and work with it.
I wouldn't do it endlessly. I would expect after a few times, you'd be able to get him to talk.
All this is assuming that the OP even wants to stay in this situation. Personally, I wouldn't. Not because I don't want to help; just because I think it's ridiculous that 4 people can't even be polite to each other after repeated encounters. You know? The "new guy" bass player is the only one who even bothered to ask the singer where he works! The other guys had been together for how long and never even thought to ask?!
That's just silly and weird to me so I wouldn't stay in that situation. Besides, don't you want to know if any of the guys in your band is a convicted axe murderer or is taking anti-depressants or something?
Strange group o' dudes. IF I was in that situation, I'd help and not worry about getting thanks right away...but I wouldn't stay in that situation anyway.
